Winter car accident fault in Ontario is assessed by examining whether each driver acted reasonably for the conditions, not simply by blaming the weather. Evidence may include road conditions, visibility, speed, right of way and the collision sequence. This guide explains the factors that may matter.
Key takeaways: Photograph conditions when safe, record weather and visibility, identify witnesses and preserve vehicle and roadway evidence.
The basic standard: a reasonable and prudent driver
In a negligence claim, a driver’s conduct is generally measured against what a reasonable and prudent driver would have done in the same circumstances. In Hill v. Hamilton-Wentworth Regional Police Services Board, 2007 SCC 41, the Supreme Court of Canada described that standard. The circumstances include the weather.
A speed or following distance that is reasonable on a dry summer day may be unreasonable on a snow-covered highway.
Driving below the speed limit is not always enough
The posted speed limit is a maximum, not a guarantee of safe driving. In Saldana v. Caruana, 2015 ONSC 4426, an Ontario court found a driver who was travelling below the posted limit on a snowy road partly responsible because they did not adjust their speed to the conditions.
At the same time, speeding does not automatically mean a driver is negligent. Courts have said, in older decisions such as Martin v. Powell (1928) and in the British Columbia case Cooper v. Garrett, 2009 BCSC 35, that speed is one factor to be considered with all of the other evidence about how the accident occurred.
Right of way does not end the analysis
Having the right of way does not relieve a driver of the duty to take reasonable care. Courts have held that a driver who sees, or should see, that another driver is not going to yield may still be partly responsible if they had a reasonable opportunity to avoid the collision. The Ontario Court of Appeal’s decision in Sekhon, 2014 ONCA 623, applies this principle.
British Columbia courts have described a similar idea, sometimes referred to as the “dominant” and “servient” driver analysis. In Knight v. Li, 2011 BCSC 184, the dominant driver was found liable where they had a reasonable opportunity to avoid the collision. British Columbia decisions are not binding in Ontario but may be considered persuasive.
Sharing fault in winter collisions
Ontario’s Negligence Act allows fault to be divided among the people who caused an accident. In winter collisions, it is common for responsibility to be shared, for example between a driver who lost control and a following driver who was too close to stop. Even a driver who was mostly blameless may have their damages reduced if they contributed to the accident.
Factors that may be considered
When fault is disputed in a winter accident, the evidence may address:
• the speed of each vehicle compared with the conditions, not just the posted limit;
• following distance and braking;
• visibility, lighting and whether headlights were used;
• whether a vehicle had appropriate tires and was cleared of snow and ice;
• road maintenance and whether the road had been plowed or salted;
• the actions of each driver once a hazard became visible.
Winter tires are not mandatory for most passenger vehicles in Ontario, but tire condition and suitability may still be relevant to whether a driver acted reasonably.
Preserving evidence after a winter collision
Weather and road conditions change quickly. If it is safe, take photos of the road surface, snow cover, signage and vehicle positions. Note the time and weather, collect witness details and keep dashcam footage. If police do not attend, document conditions as fully as possible.
Chain-reaction collisions on highways
Winter conditions on multi-lane highways can lead to chain-reaction collisions involving many vehicles. Determining fault in these cases can be complex. Each impact may need to be examined separately: which vehicle struck which, in what order, and whether each driver had a reasonable opportunity to stop. A driver who stopped safely and was then pushed into the vehicle ahead may be treated differently from a driver who failed to stop at all. Photographs of vehicle positions, damage patterns and witness accounts are particularly valuable in these cases.

Frequently Asked Questions
If I was driving under the speed limit, can I still be at fault?
Yes. Courts look at whether your speed was reasonable for the conditions. A driver below the posted limit may still be found partly at fault.
Is the weather ever to blame instead of the drivers?
Bad weather alone does not usually excuse a collision. The question is whether each driver responded reasonably to the conditions.
If I had the right of way, am I automatically not at fault?
No. A driver with the right of way must still take reasonable steps to avoid a collision they could reasonably have avoided.
Can a municipality be responsible for an unplowed road?
Possibly, but claims against municipalities involve special rules and short notice periods. Get advice promptly.
